Would you wait till after college to date your ex?

Well my ex girlfriend and I broke up last Monday after a 5months and she said that we can date after we finished college but that is a long way to go. But we still have a lot of feelings for each other and act like we are still dating. she wanted to date someone last semester and that is how we dated, but then she decides to say that we shouldn't date because of school. But if that was the case then why date in the first place because we had a good relationship and didn't get into many arguments. So in the end should I move on or continue to wait and chase after her due to us having feelings?

Updates:

I forgot to mention that I also wanted to date too. We are so similar in what we like. Plus I am her first boyfriend and she is my first girlfriend.
